    Notes: An anisotropic product angular distribution has been observed in the dissociative photodetachment of O−4 at 523 nm. Energy and angular distributions of coincident O2 products from the process O−4+hν→O2+O2+e− were measured using translational energy spectroscopy in a fast ion beam. The angular distribution peaks perpendicular to the electric vector of the laser beam. © 1995 American Institute of Physics.

    Photoelectron–neutral–neutral coincidence studies of dissociative photodetachment (1995)

    Notes: Photoelectron–neutral–neutral coincidence spectra have been measured for the dissociative photodetachment of O4− (O4−+hν→O2+O2+e−) at 523 and 349 nm. The neutral photofragment translational energy spectrum, the photoelectron spectrum, and the correlations of the translational energy and photoelectron energy are presented here. The correlation spectra reveal phenomena that are not discernable in either one-dimensional measurement. Features are observed which indicate that non-Franck–Condon processes play a role in the dissociative photodetachment of O4− at 349 nm. © 1995 American Institute of Physics.

    Translational spectroscopy studies of the photodissociation dynamics of O−4 (1996)

    Notes: An investigation of the photodissociation dynamics of the dimer anion O−4 at 523.6, 349.0, and 261.8 nm is reported. Product translational energy and angular distributions have been obtained using photofragment translational spectroscopy in a fast ion beam. At all wavelengths photodissociation (O−4+hν→O2+O−2) is observed to proceed via a rapid parallel electronic transition, with the photofragment angular distribution strongly peaked along the laser electric vector. The lowest energy photodissociation channel produces O2(a1Δg) and ground state O−2(X2Πg), indicating that O−4 is a doublet anion. The partitioning of energy in the dissociation reveals a complicated wavelength dependence. © 1996 American Institute of Physics.

    Fast-ion-beam photoelectron spectrometer (1995)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A high-collection-efficiency fast-ion-beam photoelectron spectrometer is described. In a straight time-of-flight mode, the spectrometer collects ∼1% of the photoelectrons and achieves an energy resolution of ΔE/E of ∼5%. For coincidence experiments requiring greater collection efficiency, a paraboloidal electrostatic mirror is used. The mirror collects ∼40% of the photoelectrons while maintaining ΔE/E≤35%. In both modes of operation, a time- and position-sensitive electron detector allows conversion of the photoelectron laboratory energy to center-of-mass energy. The fast-ion-beam photoelectron spectrometer is used to prepare mass- and energy-selected neutral molecules which are used in molecular dissociation studies. © 1995 American Institute of Physics.
